Application filed February 4, 1920. Serial No. 356,284.

To all 'whom it may concern.

Be it known that I, GEORGE H. QUAID, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Sash-Weight, of which thefollowing is a Specification.

y invention relates to window construction, being more particularly sashweights and the manner of connecting the weights to the sashes.

One of the principal objects of my invention is to provide a sash weightfor windows, of simple form and construction, the wei ht having a pulleywhich receives the cor the ends of the cord being connected respectivelyto the upper and lower sash, the intermediate portions of the cordbetween the sashes and the pulley being supported in the window frameabove the sash and also in providing means whereby the movement of theweight in the weight box ma be stopped and the sashes operated in suciia fashion as to counter balance each other.

Other objects and advantages will be made evident hereinafter.

Referring to the drawings which are for illustrative purposes only,

Figure 1 is a face view partly in section of a portion of a windowshowing a sash weight construction thereon embodying a form of myinvention.

Fig. 2 is a vertical sectional view through a portion of the windowframe, on line 2 2, Fig. 1.

Fig. 3 is a diagrammatic View showing the sashes, the weight and thecord connections.

Fig. 4 is an enlarged perspective view of a referred form of sash weightused, and

ig. 5 is an enlarged vertical sectional view through the locking device.

11 designates a window frame in which is mounted in the usual manner theupper sash 12 and the lower sash 13 of a window. 14.- designates a sashweight which, in its preferred form,\isvmade of concrete or othersimilar material, a rod 15 extending vertically through the weight andhaving secured to its upper end in any suitable man ner a pulley 16. Theunder face of the weight is provided with transversely arranged grooves18 which are arranged to be engaged b ribs 19 formed on the upper end ofa b ook 20 which may be placed on the rod 15 below the body 14 of theweight, the block 20 being held in place upon the rod by means of asuitable nut 21.

The under face of the block 20 is also provided with grooves 22extending across the same, and it is understood that a number of theseblocks may be placed upon the rod and supported thereon by means of thenut, the number of blocks used being governed by the amount of weightnecessary to balance the weight of the sashes so that they can be easilyoperated.

25 designates a cord which throu h the pulley 16 and over sheaves 26 and2 mounted in the window casing in any suitable manner above the sashes.One end of the cord 25 is secured to the upper end of the sash l2 andthe other end of the cord 25 is secured to the upper end of the lowersash 13.

The sash weight may be used in two different manners, that is, eitherone of the sashes 12 or 13 may be operated regardless of the other sash,in which case, the sash weight will ride vertically in the weight boxindicated at 28, which, it is understood, is placed in the window casingin the usual manner, or both sashes may be moved simultaneously by theoperation of one sash in the following manner:

Arranfred in one side of the body 14 of the weight is a metal thimble30. Upon the weight box 28 is mounted by means of suitable screws 31 abolt housing 32 in which may be placed, as shown in Fig. 5, a removablebolt 33, the inner end of which extends into the thimble 30 in theweight when the sashes are in closed position. When the bolt is inengagement with the thimble as just described the weight is lockedagainst movement in the weight box, and if for instance the lower sashis raised, the cord runs through the sheaves 26 and 27 and the pulley 16so that as the lower sash rises the upper sash moves downwardly acorresponding distance, it being understood that any manipulation of onesash through the medium of the cord imparts a like movement to the othersash in the opposite direction, the sashes balancing each other.

The bolt may be hung upon a chain 35, as shown clearly in Fig. 5, sothat the lbolt will not be misplaced when not in use.

It is understood that each side of the window embodies the sameconstruction inextends rod below the body having ribs thereon cor- 'loresponding to the grooves in seid body, :L nut on seid rod below saidblock, and :1 bolt receiving ineniher on one Side oil' said body.

In testimony whereof, l have hereunto sot my hand at Los Angeles,Californie, this 1f] 29th day of Jennery, 1920.

GEORGE H. QUAID.
